Subject: [PATCH 1/8] drm/amd/display: make some functions static

These functions are not used outside the file dcn30_resource.c, so the
modification is defined as static.

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_resource.c:1949:6: warning: no previous prototype for ‘is_refresh_rate_support_mclk_switch_using_fw_based_vblank_stretch’.
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_resource.c:1919:5: warning: no previous prototype for ‘get_frame_rate_at_max_stretch_100hz’.
